Abstract

We proposed a data compression method using the Schalkwijk code for the image processed by the minimized average error method. First of all, the dithered image is divided into some blocks, in this method. Secondly, the Schalkwijk code is applied to each divided block. In the preceding work, we used only 4 x 4 pixel size for dividing into the blocks. In this paper, we consider the various block sizes such as 3 x 1, 2 x 2, and 3 x 3. In this paper, we consider various block sizes to divide the image, and we report simulation results of compression ratio.
